description |
The bacterial infections had caused many outbreaks which affected most of the children and the elderly. Due to
the increase of bacterial resistance towards certain antibiotics, it had reduced the efficiency of current antibacterial treatments. Hence, a feasible approach needs to be done by finding more efficient drugs to treat and
control the infections that caused by the pathogenic bacteria. Several studies also had reported that chalcone can
possess the anti-bacterial, anti-fungal and insecticidal activities. In this study, instead of using chalcone, bischalcone derivatives had been applied as the new options of antibiotics in order to study the antibacterial activity
against the Gram negative and Gram positive bacteria such as Escherichia coli Ol 57:H7, Vibrio cholerae,
Bacillus cereus and Listeria monocytogenes. The anti-bacterial activity of the bis-chalcone derivatives showed
that TMH 1044 compound portrayed the lowest minimum bactericidal concentration (MBC) for all the strains
tested. Three tested compounds such as 1,3-Bis Hydroxychalcone, 1,4-Bis Hydroxychalcone and TMH I 044
showed anti-bacterial properties. The results showed that most of the compounds are more efficient in killing
Gram positive bacteria compared to Gram negative bacteria. The antibacterial activity of the bis chalcone
compound is conducted using Minimum Inhibitory Concentration (MIC) test based on micro-dilution method and
Minimum Bactericidal Concentration (MBC) test. Therefore, the application of bis- chalcone derivatives in this
study were useful as the future alternative especially in anti-bacterial treatment to control the infections caused by
the pathogenic bacteria. |
